Description
Technical Field
The present invention relates to polyethylene compositions and high density polyethylene articles and methods for making the same.
Background
The high-density polyethylene (HDPE) has good melt strength, mechanical properties and the like, and can be used for preparing products such as packaging barrels, tanks and the like by extrusion blow molding. However, the high density polyethylene has a great characteristic that the high density polyethylene has good insulation, so that static electricity is generated during storage, transportation and use, and after the static electricity is accumulated to a certain degree, violent discharge can occur to generate electric sparks. For some flammable and explosive chemical substances and environments, the electric spark is easy to cause problems such as deflagration and the like, and has certain danger. Because the polyethylene material has the characteristics of easy molding, light weight, low molding energy consumption and the like, the polyethylene material can be used for producing packaging barrels, cans and the like with good environmental protection. However, for some chemical materials for packaging which require good antistatic performance, such as spare fuel oil for off-road vehicles, military oil, etc., the packaging material is required to have good antistatic function so as to avoid the damage caused by static electricity generated during storage, transportation and use. The packaging barrel and the packaging can which are produced by adopting the antistatic polyethylene have the advantages of light weight, easiness in forming, free shape design, chemical resistance, acid-base corrosion resistance, good environmental protection and the like compared with an iron packaging barrel and a packaging can, and if deflagration and other conditions occur, the packaging barrel and the packaging can have no killing power like a metal can body and have higher safety. In general, the antistatic properties of HDPE can be improved by adding materials such as carbon black or metal powder to the HDPE. However, the addition of the carbon black makes the color of the material black, so that for products with color requirements, products with other colors cannot be prepared after the carbon black is added; if metal powder is added, firstly, the price is high, the technical powder is also easy to oxidize and can be seriously cracked, and the mechanical property of the material is poor.

In order to achieve the above object, the present invention provides a polyethylene composition comprising a high-density polyethylene, an ultra-fine fully vulcanized powdered styrene-butadiene rubber, an antistatic agent, and a compatibilizer comprising a modified polyethylene having a structural unit of a polar monomer.
The invention also provides a preparation method of the high-density polyethylene product, which comprises the following steps: the composition is extruded and molded.
The invention also provides a high-density polyethylene product prepared by the method.
By adopting the polyethylene composition, high-density polyethylene products with excellent antistatic performance and good mechanical performance can be obtained, and the color of the high-density polyethylene products obtained by the invention is light and can be adjusted, which is not the same as that of products only with black color which are prepared by adding carbon black to prepare antistatic polyethylene.
Additional features and advantages of the invention will be set forth in the detailed description which follows.
Detailed Description

The high density polyethylene may be one conventional in the art, and typically may have a density of from 0.946 to 0.976g/cm3The melting temperature may be 130-145 ℃. The high density polyethylene is commercially available, for example, from Mount petrochemical, Exxon Mobil, and the like.

The superfine fully vulcanized powdered styrene-butadiene rubber can be, for example, Narpow VP-108, a trade name of China petrochemical Beijing chemical research institute.
According to the present invention, the antistatic agent may be used in various kinds for enhancing the antistatic property of polyethylene, as long as it does not cause an excessive darkening of the color of the obtained polyethylene (if the coloration is too intense, packaging articles of various colors cannot be obtained) and a severe decrease in mechanical properties. For example, the antistatic agent may be one or more of a polymer amide antistatic agent, a polymer ether antistatic agent, a polymer amide/ether antistatic agent and an ionic polymer antistatic agent, and is preferably a polymer amide/ether antistatic agent.
Specific examples of the polymer amide/ether antistatic agent may be, for example: one or more of PEBAX MH2030 brand amide/ether antistatic agents available from Arkama, IPE rSTAT brand and IPE fSTAT brand ionic polymer antistatic agents available from IonPhasE.
According to the invention, the compatilizer can enable each ingredient in the composition to better conform to the high-density polyethylene, so that the high-density polyethylene product with better performance is obtained. The modified polyethylene having a structural unit of a polar monomer is a copolymer of ethylene and a polar monomer, and can be considered to be a modified polyethylene modified with a polar monomer. The modified polyethylene having a structural unit of a polar monomer may be one or more of an alternating copolymer, a random copolymer, a block copolymer and a graft copolymer of ethylene and a polar monomer, preferably a graft copolymer of a polar monomer as a graft structural monomer and a polyethylene as a main component (hereinafter referred to as graft polyethylene), and particularly preferably low-density polyethylene (density may be 0.91 to 0.94 g/cm)3) A graft copolymer of a predominantly polar monomer with the low density polyethylene.
Wherein, preferably, the polar monomer is one or more of maleic anhydride, methacrylate monomer and acrylate monomer. Specific examples of the methacrylate-based monomer may include, but are not limited to: glycidyl methacrylate, methyl methacrylate, ethyl methacrylate and butyl methacrylate. Specific examples of the acrylate-based monomer may include, but are not limited to: methyl acrylate, ethyl acrylate and butyl acrylate.
Preferably, the grafted polyethylene is selected from one or more of maleic anhydride grafted polyethylene, methacrylate monomer grafted polyethylene and acrylate monomer grafted polyethylene. Specific examples of the methacrylate monomer-grafted polyethylene may include, but are not limited to: glycidyl methacrylate grafted polyethylene, methyl methacrylate grafted polyethylene, ethyl methacrylate grafted polyethylene and butyl methacrylate grafted polyethylene.

More preferably, the structural unit of the polar monomer may be contained in an amount of, for example, 0.5 to 5% by weight, preferably 1 to 4% by weight, based on the total weight of the grafted polyethylene.
According to the present invention, the modified polyethylene having a structural unit of a polar monomer may be commercially available or may be prepared according to various methods conventional in the art, and for example, a modified polyethylene having a structural unit of a polar monomer may be prepared by a solution polymerization method.
Taking the preparation of grafted polyethylene as an example, the grafted polyethylene can be prepared by the following method: polyethylene, particularly low density polyethylene, is extruded with polar monomers and initiators in a reactive twin screw extruder. Among them, the method of extruding the polyethylene with the polar monomer and the initiator in a reactive twin-screw extruder is well known to those skilled in the art. For example, the three raw materials can be uniformly mixed and then fed into a reactive twin-screw extruder for extrusion; or the initiator and the polar monomer can be uniformly mixed and then the mixture of the initiator and the polar monomer and the polyethylene are extruded. Wherein, when the mixture of the initiator and the polar monomer is liquid, the mixture can be continuously added into the extruder in proportion through a liquid feeder during the extrusion process; when the mixture of the initiator and the polar monomer is a solid, the mixture of the initiator and the polar monomer may be mixed with polyethylene and then melt-extruded.
Specifically, the temperature of extrusion is 160-200 ℃, and the rate of extrusion is 200-400 g/min.
In addition, generally, the polyethylene is solid at normal temperature and pressure, and the polar monomer and the initiator may be solid or liquid. When the polar monomer and the initiator are both liquid, the mixing process of the polyethylene, the polar monomer and the initiator is easy to slip, so in order to realize molecular-level mixing of the three raw materials and be more beneficial to polymerization, the uniform mixing and melt polymerization method comprises the steps of firstly feeding the polyethylene into a reactive twin-screw extruder for melting, and then continuously adding the mixture of the initiator and the polar monomer into the extruder in proportion during the extrusion process through a liquid feeder. Wherein the feeding rate of the mixture of the polar monomer and the initiator may be, for example, 2 to 5 parts by weight/min based on 100 parts by weight of the polyethylene.
According to the invention, the amounts of polyethylene, polar monomer and initiator used in the preparation of the grafted polyethylene can be selected and varied within wide limits and can be adjusted according to the grafted polyethylene desired. For example, the polar monomer may be used in an amount of 0.1 to 5.5 parts by weight and the initiator may be used in an amount of 0.05 to 0.3 parts by weight, based on 100 parts by weight of the polyethylene. Preferably, the polar monomer is used in an amount of 1.5 to 4 parts by weight and the initiator is used in an amount of 0.05 to 0.2 part by weight, based on 100 parts by weight of the polyethylene.

Among them, it is preferable that the content of the graft copolymer of the polar monomer and the polyethylene is 10 to 100% by weight and the content of the other copolymer of the polar monomer and the ethylene is 0 to 90% by weight based on the total amount of the compatibilizer.
